Emergency lamp: permanent and unstable
Emergency lamps are indispensable assistants in situations where the main light suddenly goes out. They ensure safety and orientation in the dark, whether it is a disabling electricity during bad weather or an unexpected failure on the network. But all emergency lamps are not the same. There are two main types: constant and unstable.
Constant emergency lamps
These lamps work constantly, fuel from their own battery or battery, in parallel with the main electric network. They are always ready to work, and when you turn off light instantly turn on. Imagine a lamp such as a little friend who is always ready to help, highlighting the path in the dark. Constant emergency lamps are often used in residential buildings, offices and public places where the rapid restoration of lighting is important. They are more expensive to install, but provide continuous readiness.
Unstable emergency lamps
Unlike constant, unstable emergency lamps are activated only if the main light source is turned off. After the renewal of the supply of electricity, they automatically turn off. This is a kind of lifebuilding, which turns on only when it is needed. Such lamps are usually equipped with special sensors that respond to voltage change. They are more compact and cheaper than constant, but require additional preparation in case of sudden disconnection of light. Their use is especially justified in small rooms, where permanent energy consumption is undesirable. They, as a faithful assistant, appear only when his help is really necessary.
The choice of the lamp: what to pay attention to?
When choosing an emergency lamp, it is important to take into account the needs of the premises and your budget capabilities. A permanent lamp provides maximum readiness, but it can be too expensive in the long run. A fragile lamp is a more profitable option for some situations. It is also necessary to pay attention to the operating time of the lamp from the battery, the brightness of the lighting and the turning on/off mechanism. An attentive attitude to the choice of an emergency lamp will make your home or workplace more safe and comfortable.
